deathroller a name given to him by the lich king upon his creation. he was the lich kings LT and when he broke free of him he found new meaning in his new life a secend chance. but after the death of the lich king he has found him self fighting for controle over himself.he feels as tho a force is trying to controle him. maybe the late lich king maybe something else. only time will tell if he will keep it together. he has been trying to find who he once was when he was reborn a death knight he lost all meamorys of the life he once had,his name and who he knew he may not like what he will find when he gets to the end of the road.

The Lich King didn't die; Arthas did. Bolvar Fordragon is the new Lich King.

Death Knights now have free will, nothing could try to control him as a Lich King would have and be successful.

You can't have been one of the Lich King's lieutenants. If you were, you wouldn't have been sent to die at Light's Hope. The Acherus death knights were the only one broken from Arthas' control except for, possibly, when his heart was destroyed by Tirion.
